We extend the model orignally proposed by Unruh and Jheeta in [6] in two ways. First we
derive the complex action to third order in the slope of the slow-roll potential and find that
it depends on precisely which endpoint is chosen in complex T space, and that it also has
phase contributions to the semi-classical wave function. Secondly, we derive the reduced
Hamiltonian action to second order in classical, non-homogenous scalar metric and matter
fluctuations about an arbitrary FRW background. We analyze the I = 1 mode for the
closed FRW universe and prove it is a gauge mode. We find a contour in T space for which
this reduced action has a simple character. We use this character to make an argument
concerning the appropriateness of using Linde's or Hawking's sign in determining the
amplitude contribution to the wave-function from these classical fluctuations.
